Soybean oil is one of the most consumed vegetable oils in the world and is widely used in cooking, food processing and industrial production. So how does soybean oil turn from soybeans into clear edible oil? As one of the leading companies in the grain and oil machinery industry, Henan Huatai Cereals and Oils Machinery Co., Ltd. will give you a detailed introduction to the soybean oil processing technology and key technologies of soybean oil.
1. The main process of soybean oil processing
Soybean oil processing mainly includes pretreatment, pressing or extraction, refining and other steps, each of which directly affects the quality and yield of the oil.
1) Soybean pretreatment
Pretreatment is the first step in soybean oil processing, mainly including:
Cleaning and removing impurities: remove impurities in soybeans, such as stones, metals, straw, etc., to ensure the purity of the raw materials.
Crushing and peeling: soybeans are crushed by a crusher and the bean skins are separated to reduce the impurity content in the oil.
Softening and rolling: by adjusting the moisture and temperature of soybeans, they are softened and rolled into thin sheets for subsequent oil extraction.
2) Oil extraction (pressing or extraction)
There are two main methods for extracting soybean oil: mechanical pressing and solvent extraction.
Mechanical pressing: Using a screw oil press to physically press soybean flakes, it is suitable for small-scale production. The oil is natural but the residual oil rate is high.
Solvent extraction: Using solvents such as n-hexane to dissolve oil, it has high extraction efficiency and low residual oil rate. It is the current mainstream soybean oil extraction method.
3) Crude oil refining
The freshly extracted crude soybean oil contains impurities such as phospholipids, free fatty acids, and pigments. It needs to be refined before it can be eaten. The main steps of soybean oil refinery plant include:
Degumming: Remove phospholipids and colloids to prevent oil rancidity.
Deacidification: Neutralize free fatty acids through alkali refining to improve oil stability.
Decolorization: Use activated white clay to adsorb pigments to make the oil clearer.
Deodorization: High-temperature vacuum distillation removes odors and improves the flavor of edible oil.
